Criticker(my profile) is great for this!They are with movies a bit like we are with words; you can rank things, or just save them for later, and get (useful!) recommendations — plus, you can give your rankings names, which they call quips, and instead of friends, you have kumpels!* ..All in all, rather satisfying and dorky.

I was thinking this would be a nice place to keep all these, seeing as I have a ridiculous number of movie lists and ticket stubs collected since age 12, but now I'm wondering if I really want to publicize the information. *ponders*
